Application filed October 15,1906. Serial No. 339,137.

To all whom it may concern Be it known that I, HENRY 0. Roman, a citizenof the United States, residing at Terminal Island, in the county of Los Angeles and State of California, have invented a new and useful Ignition Apparatus for Explosion- Engines, of which the following is a specification.

This invention relates to ignition apparatus for explosion-engines.

The invention is particularly designed for marine or-launch engines wherein the use of batteries is disadvantageous; and the main object of the present invention is to employ an ignition system ,with aregular generator and with a starting-magneto and to provide for furnishing the current from either the magneto or the regular generator, the magneto being manually operated when used in starting, and when the engine is started the magneto is cut out and the regular generator cut in.

' A further object is to enable the magneto to be driven bythe engine in case of failure of the regular generator.

A further object is to provide for manually storing sufficient mechanical power in the starting-magneto to cause it to operate Without attention for-a period of time suilicient to enable the engineer to attend to the engine proper.

The magneto may be located. at any convenient or retired place in the boat-as, for example, in the bow. In starting, the engineer in casting off would be at thebowand would give the handle of the device a few revolutions, and the device would then run for a sufficient time without attention, enabling the engineer to pass astern or amidships to where'the engine is located and start .the engine, the starting-magneto running for a period of time which is ample for the purpose.

The accompanying drawings illustrate the invention, and referring thereto- .Figure 1 is a side elevation of the invention complete; Fig. 2 is a section on line :0 :c", Fig. 1. Fig. 3 is a perspective view showing the device used for connecting the magneto-shaft with the driving-shaft. Fig. 4 is adiagramm'atic view showing the manner of connecting the device with the engine. Fig. 5 is a s'idevieW showing the power attachment connected to the magneto. I .1 designates .a pair of frame-plates which are united-'bycrosabraces 2 the upper ends of the plates 1 having journals 3, in which is mounted a shaft 4, one end of which has a pin 5, which is adapted to be engaged by the notched hub 6 of a crank 7. Mounted rigidly on the shaft 4 is a driving-gear a, which meshes with a pinion b, the latter being rigidly mounted on an intermediate shaft 0, mounted in ournals 8 in the plates 1. A fiywheel 9 is rigidly mounted on the intermediate shaft 0 between the plates 1.

Extending from one of the plates 1 is a bracket 10, upon which is mounted a magneto 11, which may be of any preferred construction and having a shaft 12, which is connected with the intermediate shaft 0 by a coupling comprising a sleeve 13, having in one end anotch 14 and in the other end a notch 15, the latter being arranged at right angles with respect to the notch 14. Intermediate shaft 0 has a pin 16, which engages in the slot 14, and the shaft 1.2 has a pin 16, which engages with the notch 15. This coupling obviates the necessity of securing absolute alinement of the shafts c and 12 and insures the perfect operation of the shaft 12 without throwing any strain on the bearings, even if the magneto is not exactly in position. with the engine, as shown in Fig. 4, in which 17 designates the explosive-engine with regu- 'lar magneto 18 for furnishing the spark in the normal operation of the engine. Wires 1.9 and 20 lead from the regular magneto 18 to a double-throw switch 21. A wire 22 leads from the spark-plug of the engine to the induction-coil 23, and a wire 24 leads from the induction-coil to switch 21. Wires 25 and .26 lead from the starting-magneto to the switch 21.

When the engine is operating'normally, the switch 2] stands, as shown in Fig. 4, connecting in the wires 19 and 20. In starting the engine the switch 21 is thrown to bring the wires 25 and 26 in circuit with wire 24, self-induction coil 23, and wire 22. The crank 7 is then turned to speed up the starting-magneto, and enough energy is stored in the'fiy-wheel 9 to cause the starting-magneto -to' be run by the momentum of the fiy-wheel for a considerable time. gineer has started the starting-magneto he then gives his attention .to the, engine, and as soon asthe' en ine is working he throws the switch 21; back tonormal-position, jcutcutting in the regular dvnamo.

Thedevice may be connected ting the starting-magneto out of circuit andpower if the regular generator becomes (lisabled by employing a power connection, one

form of which is shown in Fig.-5.- "The outer end of the shaft 12- is formed with a socket- 27, wl'iich receives one end of a flexible shaft 28, the latterhaving a quill 29 for engaging in the socket, which while driving the magneto permitsnecessary end play of tlieflexible shaft while in operation. The other end .of shaft 28 is connected to a; frictin-wheel 30, carriedon a rock frame 31 and adapted toib e driven by the fly-wheel 32 of the engine 33: The frame 31 is rockedjto engage the fllGtlOIkWllGlWilih the fly-wheel by means of a lever-operated eccentric 34, which bears against the frame, the frame being retracted when released by the eccentric by a spring 35.
